While there isn't a whole lot the screws can do, think of it as resonance control of the side panels. You could, if it weren't for the holes it would leave behind and unsealing the cabinet, remove the screws from the box completely. By tightening up the screws you would raise the resonant of the side panels frequency upward. The opposite by loosening the screws.

It doesn't lower or raise the bass response per say, but lets say the desk has a frequency that it resonates at with the speakers playing, this could give you a peak if the side resonated at the same frequency, so by tightening or loosening the screws this could help with that issue.

Again, its not a profound difference, but it does help.

Make sure you use a 5/32" allen wrench on both sides of the screw at the same time. We ship them with the screws as loose as you would ever want them, so tightening would be the way to go.ZYGI

I have to get used to the sound. It is different from what I had set up in there.

The speakers are gaining in warmth and detail as they break in. I shifted their position today slightly and began to notice the computer monitor "disappearing" as I had read about before on these. I played one recording and could hear the "studio echo." This is a very accurate presentation.

I decided to pop in some 6P14P-EV tubes in the TABOO with a CV4024 Mullard in front. This is a different presentation than using a 6P15P-EV and a 5814 (12au7) in front. There is more gain to the sound so this might help with breaking in the speakers. I always seem to return to the 6P15P-EV for the CCE modification and the detail in that.

I might end up making stands to elevate the speakers a little higher, for with the other speakers I became accustomed to the tweeter firing directly at ear level.

Now half-way into the vaunted "trial period" I decided to to an A/B comparison between the TRAPEZIUM and the Von Schweikert. I wanted to make sure that the TRAPEZIUMS were keepers. I found that the Vons colored the sound, while the TRAPS let it all out. I am not certain that the TRAPS have to be elevated because they do sound better and perform better when firmly on the desk top. After the short A/B test yesterday, the Vons are going on the block and the TRAPS are staying on the desk.

Thats like music to my ears;-) Not as much the fact that they are keepers, more to the fact of what they are replacing.

Von Schweikerts are well respected and reviewed, and to think the Trapeziums are in the same league, put a smile on our faces. Pretty amazing.Mike and I had chances during our testing period to take the speaker around to a couple of different audio stores. We set them up on stands which weren't great for the bass response, due to the fact that the stands weren't wide enough to continue the port like the desk top does, but in all cases, they heard something they didn't with the name brands they carried. In some cases, the bass was better, much better defined than cabinets with 6-1/2" woofers.

Unfortunately we were never able to compare them to any Von Schweikerts.

I was in my office today (Sunday) and listened to the system a little bit. Since nobody was around I was able to turn the volume all the way up on the Taboo. It was remarkable the bass that these little speakers can slam against the desk top. I was packing up the Von Schweikert speakers to send to their new owner. I was beside the desk working on that. I would say I was about 4 feet to the left of and 3 or 4 feet away from the TRAPEZIUMS. The sound from the TRAPEZIUMS from that different vantage point was very open and natural. I had never heard them from a position other than right in front.

They have been in service 19 days now but due to being in a business setting they are only occasionally cranked up fully; sometimes near the end of the day and occasionally on the weekend. I am sure that this helps the break in.
